nently projected at external marginal extremity of second median 
nervule. Three, narrow, faint, sub-parallel, transverse lines cross 
the wing, of which the outer, crossing the nervules, is the least 
distinctly defined. The middle line runs slightly obliquely from 
costa to internal margin, just beyond the discal cell, crossing the 
median nervure at about the point at which the second and third 
m. nervules are thrown off together. Posterior wings, resem- 
bling anterior, crossed by a distinct median line, the latter corre- 
sponding to the middle line of the primaries. An outer line, pro- 
minently angulated at the middle of the wing, arising on costa at 
a point about midway between the apex and the inception of the 
middle line, and joining internal margin at about the same point 
with the latter. Fringes, on both pair of wings, pale ochreous, a 
little darker than the wings. The external margin of the seconda- 
ries is prominently medially projected. 
Under surface, a little paler than upper surface; the irrorations 
are obsolete; the two outer lines of the upper surface are here 
reproduced. 
Expanse, 9,1.55 inch. Length of body, 0.50 inch.

The palest species of the genus known to us. In the shape 
of the wings it is allied to E. fiscellaria, Guenée. The wings 
are slightly silky, but not so diaphanous as in the other species 
of the genus. The greater number of transverse lines on the 
primaries and their nearly straight and sub-parallel course, will 
distinguish this species from its congeners; the peculiar angu- 
lation of the outer line on the secondaries, following the out- 
line of the external margin, though considerably removed, is 
suggestive of the ornamentation of certain species of Endro- 
pia. In describing these species of Ellopia, the nervule emit- 
ted from the discal cross vein, is regarded as the first median 
nervule. The angulation of the external margin takes place 
at the extremity of what might be considered the median ner- 
vure itself, but which is here assumed as the second median
